Overclocking E6600 / GA-965P-S3 help

post #1 of 8
Thread Starter 
I have never overclocked anything before, but I just got a real nice heatsink and would like to try. The problem is Anytime I change my CPU Host frequency, or anything in the MIT and save cmos settings , when it reboots it just stays default.

So I think I must be doing something wrong..

My cmos looks identical to this one

http://www.xbitlabs.com/articles/mai...3_4.html#sect0


I have a E6600, 4GB Corsair XMS DDR 2 800, 1.9v


Could someone with some knowledge in overclocking tell me what my settings and voltages should be? Id like to just try a 333mhz clock to get just under 3.0ghz.

Thanks!

This is from my cheat sheet on my GA 965P-S3...

Not exactly sure if these are correct subcategories of BIOS so you will have to go thru each one and look, but this is for OC'n a C2D

_Advanced Bios_
CPU Hyper Threading - Disable
Limit CPU Max to 3 - Disable
CPU Therm Monitor - Disable
CIA2 - Disable
C1E - Disable
EIST - Disable
Virt Tech - Disable
No Exec Mem - Disable

_PC Health Status_
FAN Speed Control Method - Disable

Highlight over Inteligent Tweaker and press cntrl+F1
this enables hidden features

CPU Host Clock Control - Enable
PCIE Freq - 100
Set mem multiplier to 2
Set DRAM to Manual
set timings to its default (4-4-4-15/5-5-5-18)

Default mem voltage is 1.8 so add .1 there

vcore should be set to about 1.325 for 333 and all other aside from me should be auto. But try upping in intervals of 10.. 275-285-295 til you hit 335, then run OCCT for a 2hr CPU test..

Good Luck

Hope this helps..

thanks i got it to 3ghz from 2.4, runs great and didnt even increase my temps.. I tried a 400mhz but my machine wouldnt boot so i guess i will stay with 333, better than nothing

350 = 3.15 - 360 = 3.24 unfortunately your board has a FSB wall somewhere after that...

You may wana try clock ratio of 8 if you wana go higer than 3.24..

ratio 8 - 425 = 3.4 - 437 = 3.5 - 450 = 3.6

I have seen ppl run it with 450x8, just never could myself with an E4300, best I did was 360x9 - 3.24 - 1.375v (bios)

glad you got it working tho...

the F12 bios fixes the "no post issue" when overclocking

thanks for the info on the f10 bios i will have to try

I do have one question regarding the core voltage.

From what I have read I understand you want to keep this under 1.5v to prevent damage?

in the bios I have mine set to 1.35 which is the default.

In CPU-Z however it reads out at 1.472 however my cpu is sitting at a 39 cel load which is great so I think i can go higher than this 3.0ghz however im worried about what that core voltage? do i want to modify this in the bios to go higher?

And also if I try the clock ratio 8 method 425mhz , do I want to keep my ram at 1:1? 667mhz?

You need to set your cpu voltage, dont leave it at auto.. Auto will cause it to raise to account for the higher freq. try it set at 1.35 it will read higher in windows, but souldnt be that much higher.. if it is set to 1.35 and reading 1.47, try to lower it to say 1.3175-1.325 and doo a stress test for a couple hours. 1.5 is max voltage, but id recommend no higher than 1.475 in bios or windows

leave your mem multi at 2.0 if you go to 425 that will run it at 1:1 and 850mhz (425x2), you may have to loosen your timings to 5-5-5-18. right now its at 1:1 and 333x2 (667) in which case you should run it at 4-4-4-15 (or lower if possible) lower timings = faster read-write time

I currently have my memory at 5-5-5-18 , its standard for this memory anyway

I tried 425 ratio 8 and it shows 3.4ghz at post but then immidiatly shuts down and resets itself to default so thats a no go I guess?

Whats the next jump in the ratio 9s I could try after 333? noticble increase that is and what should I set my volt to for it.


I did manually set my volt to 1.35 and your right its now at 1.37 in CPU-Z so good news there.

thanks

9x multi try 350 then 360

unfortunately that board has troubles above that
